Villars meanwhile was in a transport of delight. He drew every man not only from all parts of the lines but also from the neighbouring garrisons towards the threatened point, and asked nothing better than that Marlborough should attack. In the height of exultation he actually wrote to Versailles that he had brought the Duke to his ne plus ultra. Marlborough's strange manner still remained the same. On the 2nd of August he advanced to within a league of the lines, and during that day and the next set the whole of his cavalry to work to collect fascines. At nightfall of the 3rd he sent away all his light artillery, together with every wheeled vehicle, under escort of a strong detachment, and next morning rode forward with most of his generals to reconnoitre the lines. Captain Parker of the Eighteenth Royal Irish, who had obtained permission to ride with the Staff, was amazed at the Duke's behaviour. He had now thrown off all his ill-temper and was calm and cool as usual, indicating this point and that to his officers. "Your brigade, General, will attack here, such and such brigades will be on your right and left, such another in support, and you will be careful of this, that, and other." The generals listened and stared; they understood the instructions clearly enough, but they could not help regarding them as madness. So the reconnaissance proceeded, drearily enough, and was just concluding when General Cadogan turned his horse, unnoticed, out of the crowd, struck in his spurs and galloped back to camp at the top of his speed. Presently the Duke also turned, and riding back very slowly issued orders to prepare for a general attack on the morrow.

At this all ranks of the army, from the general to the drummer, fell into the deepest depression. Not a man could fail to see that direct attack on the lines was a hopeless enterprise at the best of times, and doubly hopeless now that half of the army and the whole of the artillery had been detached for other service. Again the violent and unprecedented outburst of surliness and ill-temper was difficult to explain; and the only possible explanation was that the Duke, rendered desperate by failure and misfortunes, had thrown prudence to the winds and did not care what he did. A few only clung faintly to the hope that the chief who had led them so often to victory might still have some surprise in store for them; but the most part gave themselves up for lost, and lamented loudly that they should ever have lived to see such a change come over the Old Corporal.

So passed the afternoon among the tents of the Allies; but meanwhile Cadogan with forty hussars at his heels had long started from the camp and was galloping hard across the plain of Lens to Douay, five leagues away. There he found Hompesch ready with his garrison, now strengthened by detachments from Bethune and elsewhere to twelve thousand foot and two thousand horse, and told him that the time was come. Hompesch thereupon issued his orders for the troops to be ready to march that night. Still the main army under Marlborough knew nothing of this, and passed the day in dismal apprehension till the sun went down, and the drummers came forward to beat tattoo. Then a column of cavalry trotted out towards the Allied right, attracting every French eye and stirring every French brain with curiosity as to the purport of the movement. Then the drums began to roll; and the order ran quietly down the line to strike tents and make ready to march immediately.

Never was command more welcome. Within an hour all was ready and the army was formed into four columns. The cavalry having done their work of distracting French vigilance to the wrong quarter returned unseen by the enemy; and at nine o'clock the whole army faced to its left and marched off eastward in utter silence, with Marlborough himself at the head of the vanguard.

The night was fine, and under the radiant moonlight the men swung forward bravely hour after hour over the plain of Lens. The moon paled; the dawn crept up into the east throwing its ghastly light on the host of weary, sleepless faces; and presently the columns reached the Scarpe. So far the march had lasted eight hours, and fifteen miles had been passed. Pontoon-bridges were already laid across the river, and on the further bank, punctual to appointment, stood Brigadier Sutton with the field-artillery. The river was passed, and presently a messenger came spurring from the east with a despatch for the Duke of Marlborough. He read it; and words were passed down the columns of march which filled them with new life. "Generals Cadogan and Hompesch" (such was their purport) "crossed the causeway at Arleux unopposed at three o'clock this morning, and are in possession of the enemy's lines. The Duke desires that the infantry will step out." The right wing of horse halted to form the rearguard and bring up stragglers, while a cloud of dust in the van told that the Duke and fifty squadrons with him were pushing forward at the trot. Then the infantry shook themselves up and stepped out with a will.

Villars had received intelligence of Marlborough's march only two hours after he had started, but he was so thoroughly bewildered by the Duke's intricate manœuvres that he did not awake to the true position until three hours later. Then, quite distracted, he put himself at the head of the Household Cavalry and galloped off at full speed. So furiously rode he that he wore down all but a hundred of his troopers and pushed on with these alone. But even so Marlborough was before him. At eight o'clock he crossed the lower causeway at Aubanchoeuil-au-bac and passing his cavalry over the Scarpe barred the road from the west by the village of Oisy. Presently Villars, advancing reckless of all precautions, blundered into the middle of the outposts. Before he could retire his whole escort was captured, and he himself only by miracle escaped the same fate.

The Marshal now looked anxiously for the arrival of his main body of horse; but the Allied infantry had caught sight of them on the other side of the Sensée, and weary though they were had braced themselves to race them for the goal. But now the severity of the march and the burden of their packs began to tell heavily on the foot. Hundreds dropped down unconscious and many died there and then, but they were left where they lay to await the arrival of the rearguard; for no halt was called, and each regiment pushed on as cheerfully as possible with such men as still survived. Thus they were still ahead of the French when they turned off to the causeway at Arleux, and, Marlborough having thrown additional bridges over the Scarpe, they came quickly into their positions. The right wing of infantry crossed the river about four o'clock in the afternoon, having covered close on forty miles in eighteen hours; and by five o'clock the whole force was drawn up between Oisy and the Scheldt within striking distance of Arras, Cambrai, and Bouchain. So vanished the ne plus ultra of Villars, a warning to all generals who put their sole trust in fortified lines.

July 27
August 7.

Marlborough halted for the next day to give his troops rest and to allow the stragglers to come in. Fully half the men of the infantry had fallen out, and there were many who did not rejoin the army until the third day. Villars on his side moved forward and offered Marlborough battle under the walls of Cambrai; but the Duke would not accept it, though the Dutch deputies, perverse and treacherous to the last, tried hard to persuade him. Had the deputies marched in the ranks of the infantry with muskets on their shoulders and a kit of fifty pounds' weight on their backs, they would have been less eager for the fray. Marlborough's own design, long matured in his own mind, was the capture of Bouchain, and his only fear was lest Villars should cross the Scheldt before him and prevent it. Then the deputies, who had been so anxious to hurry the army into an engagement under every possible disadvantage, shrank from the peril of a siege carried on by an inferior under the eyes of a superior force. But Marlborough, even if he had not been able to adduce Lille as a precedent, was determined to have his own way, and carried his point. At noon on the 7th of August he marched down almost within cannon-shot of Cambrai, ready to fall on Villars should he attempt to cross the Scheldt, halted until his pontoon-bridges had been laid a few miles further down the stream, and then gradually withdrawing his troops passed the whole of them across the river unmolested.
